The Croatia international only secured a switch to Russia in July, penning a three-year contract upon his arrival.
It is, however, possible that he could be on the move again in January, with interest in his services steadily mounting.
Schildenfeld claims a number of bids have already been put on the table, with teams from across Europe expressing an interest in acquiring his services.
"I have some options and I'm really happy because of that," he told Sportske Novosti.
"I could go to Greece, to Germany, to France and even to England. The offer from the Premier League is really interesting.
"I can't tell you which club wants me, as I have been told not to talk about negotiations, but I believe everything will be resolved in the next two months."
